When i first noticed this while driving it was a lg glowing ball with a long tale. Ball was about the size of my fist with arm stretched out. I was in a very open area with clear skies and observed it for about 1/3 to about 1/2 of the visible sky. It moved very rapidly across the sky and seemed to drop sharply as it neared the horizon. An illusion i suspect.
